Application ned March v, 1906. serial No. 304,759.

To @ZZ whom, if may concern:

Be it known that I, JOHN K. Horn), a citizen of the United States,residing at Silver City, in the county of Yazoo and State ofMississippi, have invented a new and useful Wrench, of which thefollowing is a specification.

This invention relates to wrenches and its object is to provide a wrenchwith which is combined means for upsetting metal for the purpose ofholding a nut against rotation after it has been turned into desiredposition by means of the wrench.

A still further object is to provide a wrench having means whereby metalwhich has been upset in this manner can be cut away or removed so as topermit the nut to be unscrewed.

With the above and other objects in view the invention consists of awrench having a jaw at each end adapted to embrace a nut, so that thesame may be readily turned. passage is formed through the wrenchadjacent each jaw, and in one of these passages is a springsupportedplunger so shaped that when driven downward it will cut into the surfaceagainst which the nut has been turned and if said surface be of metalwill upset it, so as to overlap the nut and prevent it from rotating.Another plunger is mounted adjacent the other jaw of the wrench, andthis is so shaped that by placing the jaw upon the locked nut and thenstriking the plunger with a hammer the upset portion will be cut away,so as to permit the nut to be unscrewed. The wrench is particularlyadapted for tightening and locking the nuts of rail-joints, and byutilizing the same the nuts can be tightened and then securely lockedsimply by striking the proper plunger, so as to upset a portion of themetal of the fish-plate to cause it to overlap the nut and hold 1t.

The invention also consists of certain other novel features ofconstruction and combinations of parts, whichwill be hereinafter morefully described, and pointed out in the claims.

In the accompanying drawings is shown the preferred form of myinvention.

In said drawings, Figure 1 is a prespective view of the wrench. Fig. 2is a section through the ends thereof, the plungers being shown in theirnormal positions. Fig. 3 is a section through one end .of the wrench andshowing the osition of the plunger while upsetting meta to lock a nut.Fig. 4'is a similar view through the other end of the wrench and showingthe position of the othervplun ger while flattening the upset metal, anFigs. 5 and 6 are detail views of the two plun ders.

c Referring to the figures by numerals of reference, 1 is a shank havingjaws 2 and 3 at the ends thereof, said jaws being similar and so shapedas to embrace a nut. Extending obliquely through the jaw 2 is a passage4, said passage being located close to one side .of the jaw, and withinthe same is slidably mounted a plunger 5, having ahead 6, against whichbears one end of a lspring 7, mounted on the jaw. The other end of theplunger is beveled, as shown at 8, to form a rounded cuttin edge 9,disposed in a plane nearly paralle to the longitudinal center of theplunger. Said plunger is loosely mounted within the passage and islimited in its movement by a screw 10, which projects into an elongatedrecess 11, formed within lthe plunger. Another passage 12 extendsobliquely through the other jaw 3, and the lower end of this passageopens through one wall of said jaw. plunger 13 is mounted within thispassage 12 and has a head 14 at its outer end, a spring 15 beinginterposed between said head and the jaw for the purpose of supportingthe plun er. The lower portion of the plunger is beve ed to form astraight cutting edge 16, adapted to move within that portion of thepassa e extending through the wall of jaw 3.

. The p unger is limited 1n its movement by a screw 17, which projectsinto the passage 12 and into an elongated recess in the plunger.

In using the wrench the jaw 2 is first placed upon a nut 19, and byturning the wrench said nut can be screwed tightly against thefish-plate 20. After its limit of movement has been reached the plunger5 is driven toward the fish-plate by striking it with a heavy hammer. Asthe lower end of this plunger is beyeled and as the entire plunger isloosely mounted within its passage 4 it will be obvious that when theplunger is forced inward against the fish-plate it will slide toward thenut as it cuts into the fish-plate, and therefore a portion of the metalof the fishplate will be raised or upset to form a lug 21, which willoverlap the nut and prevent it from unscrewing. Should it be desired toremove the nut, the other jaw of the wrench is placed thereon, so thatthe plunger 13 will rest upon the lug 21. Said plunger is then driveninward by means of a heavy hammer and IOO IIO

will remove the lug from the path ofsaid nut, which can then beunscrewed.

'le I have shown the two lungers connected to the same shank, it willDof course be understood that two separate tools may be made, one beingprovided with the upsetting plunger and the other withthe plunger 13.

By utilizing a device such as herein described it becomes unnecessary toemploy nut-locks and practically no more time is necessary for tigtening the nuts and locking them than is usually necessary fortightening them alone.

What is claimed is l. The combination with a wrench; of anupsetting-tool slidably mounted within the wrench adjacent the jawthereof.

2. The combination with a wrench, of a spring supported upsetting toolslidably mounted therein adjacent the jaw.

3. The combination with a Wrench; of a spring supported upsetting toolslidably mounted therein adjacent the jaw thereof, and means forlimiting the movement of the too 4. The combination with a shank havingsimilar aws at the ends thereof, of an upsetting-tool slidably mountedadjacent one of the jaws, and a cutting-tool slidably mounted Intestimony that I claim the foregoing as 4 my own I have hereto aflixedmy slgnature in the presence of two witnesses.
